Ground-based detection of an extended helium atmosphere in the Saturn-mass exoplanet WASP-69b
Lisa Nortmann, Enric Pallé, Michael Salz +25
Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation, affecting their physical and chemical evolution. Studies of atmospheric escape from ex…
Detection of He I Å absorption on HD 189733 b with CARMENES high-resolution transmission spectroscopy
M. Salz, S. Czesla, P. C. Schneider +35
We present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto. A strong absorption signal is detected in the near-infra…
Multiple water band detections in the CARMENES near-infrared transmission spectrum of HD 189733 b
F. J. Alonso-Floriano, A. Sánchez-López, I. A. G. Snellen +27
Aims: We explore the capabilities of CARMENES for characterizing hot-Jupiter atmospheres by targeting multiple water bands, in particular, those at 1.15 and 1.4 m. Hubble Space…
CARMENES input catalogue of M dwarfs IV. New rotation periods from photometric time series
E. Diez Alonso, J. A. Caballero, D. Montes +21
Aims. The main goal of this work is to measure rotation periods of the M-type dwarf stars being observed by the CARMENES exoplanet survey to help distinguish radial-velocity signal…
Calibrating the metallicity of M dwarfs in wide physical binaries with F-, G-, and K- primaries - I: High-resolution spectroscopy with HERMES: stellar parameters, abundances, and kinematics
D. Montes, R. González-Peinado, H. M. Tabernero +7
We investigated almost 500 stars distributed among 193 binary or multiple systems made of late-F, G-, or early-K primaries and late-K or M dwarf companion candidates. For all of th…
CARMENES input catalogue of M dwarfs: III. Rotation and activity from high-resolution spectroscopic observations
S. V. Jeffers, P. Schoefer, A. Lamert +18
CARMENES is a spectrograph for radial velocity surveys of M dwarfs with the aim of detecting Earth-mass planets orbiting in the habitable zones of their host stars. To ensure an op…
